Excavator Cleaning Mud Skills Sharing

The position of the release device is very important. From the above, the hand must be slow, and the heart can't eat hot tofu. It is best not to use wheeled excavators in silt environments because wheel excavators can easily get stuck in the mud, unlike crawler excavators. It is more flexible and slippery in some ways. When the road is walking, it is easy to slip and unnecessary property loss occurs.

In this case, the best construction machinery partner is a track widening excavator, which is marked "LC" on cars and loaders. Because even if the crawler excavator is now in the mud, use an excavator to pull the mud around the excavator to the side, and then pull it out with a larger horsepower loader. This is also an important point.

In the case of deep mud, we usually use steel excavators, small excavators with around 1-2 steel plates and 200 excavators with 3-4 steel plates. However, when using an excavator to pick up steel plates, this is not a problem for drivers with rich driving experience, but for excavator apprentices and novices, this is really difficult, but as long as everyone has mastered the steel plate, The skill is that the steel plate can be easily picked up in this work.

The preparatory movement of the steel plate is the same as the preparation operation when the excavator performs the leveling operation. First, find the right place for the excavator and move on to the next step.

Next, gently turn the blade of the bucket to the outside, and then slowly extend the shovel under the steel plate to reach about 1/3 of the steel plate.

In the third step, slowly move the bucket to the inside, then lift the starter arm up and then extend the arm outwards, as this will prevent the steel plate from being lifted and hit the excavator once. Cab.

The technique for selecting steel plates is as described above. There is also the fact that the excavator driver's friend is required to pay attention to the fact that when the steel plate is placed, it is impossible to turn the excavator to a certain position and rotate the bucket. The steel plate is heavy. If it is as easy as tamping soil, it is easy to roll the excavator due to the weight of the steel plate.

When we put the steel plate in, we can extend the arm slightly to the side of the cab. If the distance of the arm is too far, the machine will roll the object.

Measures To Prevent Excavators From Falling Into The Mud

When it comes to excavators, there are many opportunities in the South and fewer opportunities in the North. Places that are often trapped are usually places with more water. There are groundwater, rainwater, lakeside, fish ponds, digging foundations, and unloading. In the yard, eradicating the excavator is both cumbersome and laborious. It may also be accompanied by tracks, so how to avoid and get rid of it. Let's discuss it below.

To the above, where the soil may be soft, you must first test it, push it down with a bucket, try not to enter more than four-fifths of the bucket, and the chain of your own excavator. To have a full understanding, you must always leave yourself behind the road. It is not good to ask other drivers at the construction site to improve their feelings. Peers will help each other.

In order to get rid of the fault, the excavator should always be kept as flat as possible and adjusted in time. Excavators are difficult to move in the mud. Basically, it is necessary to use the power of the bucket to move forward. Remember, the excavator cannot be supported too high. The deeper the support, the deeper the support. Sometimes it can be removed. The excavator was stuck because the bracket was too high. Other excavators cannot be pulled out. The turntable is stuck and the ground is inside. It is also mud, try to adjust to a straight line, steel plate is the best, you can also use cement blocks, large, rescue methods are generally in the middle and sides of the excavator mud.

Excavator Driver Needs To Know The Excavator Trenching Skills

Trenching is one of the skills that an excavator operator must master. It is not easy to master this skill. In the process of digging trenches, many operators will have problems with different grooves and different depths. So what are the operational skills of trenching?

1. Progressively digging trenches

When starting to dig trenches, start from the surface layer and dig one layer at a time. Don't try to dig it all at once, especially when the trench to be dug is deep. In addition, when digging a trench larger than the width of the bucket, it is necessary to dig both sides and then dig the middle.

2. The route for trenching must be straight

The most important thing about trenching is to follow the principle of straightening. Generally, it will be drawn with lime lines before excavation. The center line of the excavator and the middle of the bucket are aligned with the lime line.

3. Control of the bottom of the ditch

The control of the bottom of the ditch is crucial. At this time, you need to use the techniques of square and leveling. If the trenching is to install a water pipe drain, a certain slope is required at the bottom; if it is a foundation pit, the bottom level is required.

4. Maintain the flatness of the slope on both sides of the ditch

Many novice digging trenches are not well boring, mainly because the principle of tidying is not done, and the detailed operation needs to be further improved. From the beginning of the V-shaped ditch to the end, the slope should maintain the same slope. Of course, the soil and the depth of the ditch are different, and the slope needs to be adjusted accordingly. In addition, the operator must pay attention to the loose soil around the ditch to prevent the soil from falling, and should be cleaned with a bucket in time.

Here are three ways to dig trenches:

1. Shunbian: It refers to a narrow area of ​​the site. Like a clear channel, the bucket only digs along the side track line.

2. Alignment type: Mainly for the excavation of the road culvert trench, it means that the excavator and the ditch side are parked at 90 degrees.

3. Riding and digging: mainly the open area of ​​the site, the excavator is parked in the middle of the trench to be excavated, and the bucket is dug in the middle of the two crawlers.

Analysis of The Causes of Damage To The Excavator Track

The excavator's track is an important part of the excavator. Since the working environment of the excavator is mostly bad, it is inevitable that the excavator's track will be damaged by large and small ones. What are the reasons for the damage of the excavator's track? Let us analyze it below.

1. Long walk
Due to the special structure of the excavator, it is impossible to walk for a long time. This will not only cause great damage to the crawler but also affect the service life of the equipment. Therefore, the excavator should travel as little as possible.

2. Improper operation when turning
When the excavator is turning, the crawler on one side is moving and the crawler on the other side is stationary, and the moving crawler will have a large rotation. At this time, if the static crawler is blocked by the raised part on the ground, The track is caught on the side of the rotating side and the track is easily pulled.

3. Failure to clean up the gravel in the track in time
When the crawler excavator is working or moving, some gravel or mud will enter the track. If it is not removed in time before walking, the gravel will be squeezed on the driving wheel and the guiding wheel as the interest rate belt rotates. Between the track and the track, the time will make the track of the excavator loose, and the chain rail will break. Therefore, we must check and clean up in time.

4. Excavator parking is not reasonable enough
When the crawler excavator is parked, it must be parked in a flat place. If the height is uneven, it will cause the track of the excavator to be unevenly loaded, which may cause the track to break.

5. Driving on uneven roads
The working environment of the excavator is generally uneven. Under such terrain conditions, the crawler excavator travels improperly, the weight of the body tends to be partial, and the local pressure becomes large, which may cause the crawler to loosen.

Things To Be Aware of When The Excavator Goes Up And Down

Excavating uphill and downhill is a dangerous and difficult operation for many excavator masters. In order to reduce the occurrence of accidents when excavating the excavator, it is necessary to master some operational skills. Let's share with you some notes about the excavator's ups and downs for your reference!

1. Carefully observe the surrounding situation

First, the excavator must carefully observe the ramp before going up and down. It has a preliminary judgment on the angle of the ramp and the texture of the ramp, and determines whether the climbing is within the controllable range of the excavator operation. In addition, the road surface is too slippery to fit downhill.

2. Remove stones before going up and down the slope

Whether it is uphill or downhill, you must first remove the obstacles around you, especially to remove larger stones. When climbing, not a large stone will make the excavator track slip, and an accident will occur. it is too late.

3. Remember to fasten your seat belt

Most excavator masters do not have the habit of wearing seat belts, but when downhill, if there is no seat belt, the handle is easy to dump forward. So be sure to fasten your seat belt downhill.

4. Up and down slopes should be facing the slope

The excavator climbs the slope directly to the slope, and it is best not to turn on the slope, which is easy to cause rollover or landslide. Whether it is uphill or downhill, remember that the cab must face in the forward direction.

5. Don't forget to put down the bucket up and down the slope

When the excavator goes up and down, there is one more point to pay special attention to, that is, put the bucket of the excavator down and keep it about 20~30cm away from the ground, so that when there is a dangerous situation, the bucket can be put down immediately to keep the excavator Stabilize and let it stop sliding down.

6. Try not to park on the ramp

The excavator is best parked on a flat surface. When it is necessary to park on the ramp, gently insert the bucket into the ground, open the digging arm (about 120 degrees), and place the stopper under the track.

Excavator Walking Matters Need Attention to Avoid Rollover

During the operation of the excavator, the situation of the excavator rollover occurs due to the driver's operation or environmental conditions. Therefore, for your reference, we summarize some of the problems that the excavator needs to pay attention to during walking.

1. When reversing the excavator, it is necessary to predict the parking space in advance. It is best to ask someone to direct behind.

2. The excavator should walk straight on the ramp as far as possible while the bucket is at a certain distance from the ground. If there is a slipping, roll, etc., lower the bucket immediately. If there is a stall stop on the ramp, place the bucket on the ground immediately, place the lever in the neutral position, and restart the engine.

3. Before the excavator walks, check the road surface, clear the obstacles on the road, let the unrelated personnel stay away from the excavator, and then raise the bucket to start the excavator.

4. When the excavator is walking, try to choose a flat road surface to avoid the rotation of the upper turntable. When walking on a bad ground, avoid the hard object from hitting the travel motor and the crawler frame.

5. Check the direction of the track frame before starting to determine the position of the drive wheel.

6. Try to avoid the excavator walking in the water. If it is necessary to launch the water, be sure to check the depth of the water and the hardness of the bottom of the water in advance. If the underwater mud is too deep, or the water surface exceeds the track, it is not suitable to walk.

7. The driver should control the walking speed according to the road condition. When walking on the open flat ground, you can select “1”, and you can select “0”when going up and down.
